[OPENMP] Codegen for 'firstprivate' clause in 'sections' directive.
If there are 2 or more sections in a 'section' directive the following code is generated:
<init for firstprivates>
@__kmpc_cancel_barrier();// To avoid data race in firstprivate init
@__kmpc_for_static_init_4();
<BODY for sections directive>
@__kmpc_for_static_fini()
If there is only one section, the following code is generated:
if (@__kmpc_single()) {
<init for firstprivates>
@__kmpc_end_single();
}
@__kmpc_cancel_barrier(); // To avoid data race in firstprivate init
